DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to FIG. 1, a vehicle 10 with a vehicle passenger compartment vent structure 12 (FIG. 2) is illustrated in accordance with a first embodiment.

As shown in FIG. 1, the vehicle 10 is a pick-up truck sometimes referred to as a King Cab truck. It should be understood from the drawings and the description herein that the vehicle 10 can be any of a variety of vehicle designs, such as, for example, an SUV (sports utility vehicle), a crew-cab pick-up truck or a van.

The vehicle 10 includes a vehicle body structure 14. As shown in FIGS. 1-4, the vehicle body structure 14 includes a roof structure 16, A-pillars 18 (only one shown), C-pillars 20, a floor 22 and a rear wall structure 24. The roof structure 16, the A-pillars 18, the C-pillars 20, the floor 22 and the rear wall structure 24 define a passenger compartment 28. The roof structure 16, the A-pillars 18 and the C-pillars 20 define door openings 30 that receive front doors 32 (only one shown in FIG. 1) and rear doors 34 (only one shown in FIG. 1). In the depicted embodiment, the vehicle body structure 14 does not include B-pillars. Rather, the rear doors 34 include latch mechanisms that engage respective sills 36 and roof rails 38 below and above the door openings 30. The front doors 32 include latch mechanisms (not shown) that engage the rear doors 34 and/or the sills 36 and roof rails 38, in a conventional manner. The front and rear doors 32 and 34 are common to King Cab vehicle designs, since King Cab design has become a conventional configuration. Consequently, further description of the front and rear doors 32 and 34 is omitted for the sake of brevity.

As shown in FIG. 1, front seats S_(F) and rear seats S_(R) are visible through windows in the front door 32 and the rear door 34. In subsequent drawings the front seats S_(F) and the rear seats S_(R) are removed for greater clarity of the features of the vehicle passenger compartment vent structure 12.

As shown in FIGS. 2, 3 and 4, the rear wall structure 24 includes an upper area that defines a rear window opening 42 and a lower area 44. The rear wall structure 24 basically defines a rearward area of the passenger compartment 28 of a vehicle 10. The rear window opening 42 is defined between the C-pillars 20, above the lower area 44 and below the roof structure 16. The floor 22 extends forward from a bottom end of the rear wall structure 24. The lower area 44 includes and partially defines the vehicle passenger compartment vent structure 12, as is described in greater detail below.

As shown in FIGS. 2 and 3, the vehicle passenger compartment vent structure 12 (hereinafter the vent structure 12) is primarily located on or adjacent to the lower area 44 of the rear wall structure 24. Specifically, the vent structure 12 is defined by features of the lower area 44 of the rear wall structure 24, features of a rear trim panel 50, drafter vent assemblies 52 and baffles 54.

As shown in FIGS. 3, 4 and 5, the lower area 44 of the rear wall structure 24 extends from a lower end of the window opening 42 to the floor 22. As shown in FIGS. 2, 3 and 6, the rear trim panel 50 covers the lower area 44 of the rear wall structure 24 when fully assembled. However, as shown in FIG. 4 with the rear trim panel 50 removed, the lower area 44 includes at least one vent opening 58, and preferably two vent openings 58, a jack caddy 60 and laterally extending seals 62.

As shown in FIG. 4, the vent opening 58 extends from the passenger compartment 28 to the exterior of the vehicle body structure 14 through the rear wall structure 24. The jack caddy 60 is a conventional structure installed to the rear wall structure 24 to support a jack (not shown) for supporting and lifting the vehicle 10 in order to change a flat tire and a lug wrench (not shown). Since jack caddies, jacks and lug wrenches are conventional vehicle elements, further description is omitted of the sake of brevity.

The laterally extending seals 62 are installed to the lower area 44 of the rear wall structure 24 below and spaced apart from the window opening 42. The laterally extending seals 62 can be made of a single resilient material or can be made with a bracket portion that attaches to the rear wall structure 44 with a seal portion installed along a laterally extending forward end of the laterally extending seals 62. The laterally extending seals 62 are dimensioned such that when the trim panel 50 is installed to the rear wall structure 24, the laterally extending seals 62 contact the trim panel 50 creating an air tight seal therebetween. The laterally extending seals 62 at least partially define an air flow path (also referred to as an air outlet passageway) that includes at least three pathways A₁, A₂ and A₃, as explained in greater detail below.

As shown in FIGS. 2, 3, 6, 8-10 and 14, the rear trim panel 50 includes two recessed areas that conform to overall shapes of the rear seats S_(R) (description of the two recessed areas is omitted for the sake of brevity). The rear trim panel 50 further includes an opening 70 (FIG. 8-10), outboard baffles 72, reinforcement webs 73, inboard baffles 74 (FIGS. 5 and 8), sealing blocks 75 (FIG. 9), a removable cover 76 (FIGS. 2, 3 and 6), and an upper sealing edge 78 (FIGS. 8 and 12). The rear trim panel 50 also includes a trim surface 50 a (FIGS. 2, 3, 6 and 14) that is exposed within the passenger compartment 28 and a rear surface 50 b (FIGS. 8-10) that is hidden from view with the rear trim panel 50 installed to the rear wall structure 24.

The opening 70 (FIGS. 8-10) is dimensioned such that a passenger or vehicle operator can remove the removable cover 76 from the rear trim panel 50 (with the rear trim panel 50 installed to the rear wall structure 24). Once the cover 76 (also referred to as a removable access panel) is removed, the jack caddy 60 (also referred to as a tool caddy) is exposed and can be accessed. With the cover 76 installed to the rear trim panel 50, the jack caddy 60 and the tire changing tools stored thereon are concealed. As shown in FIG. 8, the rear surface 50 b of the rear trim panel 50 includes the outboard baffles 72, the reinforcement webs 73 and the inboard baffles 74.

As shown in FIGS. 8 and 10, the outboard baffles 72 are basically flanges formed with, or alternatively, attached to the rear surface 50 b of the rear trim panel 50. The outboard baffles 72 are vertically oriented and spaced apart from the adjacent lateral edge of the rear trim panel 50. As shown in FIG. 9 with elements of the rear wall structure 24 superimposed on the rear trim panel 50, the outboard baffles 72 are located inboard and adjacent to an inboard side of a corresponding one of the drafter vent assemblies 52. Like the laterally extending seals 62, distal ends of the outboard baffles 72 have thick sealing material fitted thereto. Hence, the outboard baffles 72 are also referred to as seals and sealing structures. Thus, when the rear trim panel 50 is installed to the rear wall structure 24, the sealing material on the outboard baffles 72 seals against a forward-facing surface (interior surface) of the rear wall structure 24 at least partially defining the pathways A₂ and A₃ of the air flow path.

As shown in FIG. 8, the reinforcement webs 73 are optional structures that stiffen the central portion of the trim panel 50 in the area s on either side of the opening 70. The reinforcement webs 73 are preferably integrally formed with the trim panel 50. As shown in FIG. 9, the sealing blocks 75 (one for each of the reinforcement webs 73) are placed on and/or adhered to the reinforcement webs 73. Alternatively, the sealing blocks 75 can be installed to the rear wall structure 24 in locations that overlap with and/or align with the reinforcement webs 73. In the depicted embodiment, the sealing blocks 75 are fixed to the reinforcement webs 73 and contact the rear wall structure 24 with the trim panel 50 installed to the rear wall structure 24. Contact between the rear wall structure 24 and the sealing blocks 75 creates an air seal there between. The inboard baffles 74 are located below respective ones of the reinforcement webs 73 and include seals installed to distal ends thereof. Further, the inboard baffles 74 are located on opposite sides of the opening 70. With the trim panel 50 installed to the rear wall structure 24, the inboard baffles 74 also contact the rear wall structure 24 creating an air seal therebetween.

The upper sealing edge 78 can be provided with a sealing material (not shown) and attachment fasteners (not shown). Consequently, the rear trim panel 50 can be installed to the rear wall structure 24 and fixed in place in a conventional manner with fasteners. Once the rear trim panel 50 is installed to the rear wall structure 24, as shown in FIG. 12, the upper sealing edge 78 contacts the rear wall structure 24 and creates an air seal therebetween.

The cover 76 includes vent openings 79 as shown in FIGS. 2, 3 and 10). The vent openings 79 are louvred vent openings, and define the beginning of the airflow pathway, and more specifically, the pathway A₁. In other words, when an air conditioning/heating system of the vehicle is operating, air pressure within the passenger compartment 28 increases, the air pressure is relieved with air flowing out of the passenger compartment 28 through the vent openings 79 in the cover 76 and into the pathway A₁. FIGS. 3, 5 and 10 show the general directions of air flow of the pathways A₁, A₂ and A₃. When air conditioning or heat is being provided to the passenger compartment 28 in a non-recirculating mode with fresh air being cooled or heated, the blower motor (not shown) moves air into the passenger compartment 28. In order to prevent an excessive or undesirable amount of air pressure within the passenger compartment 28, air moves through the vent openings 79 and into the air flow path defined between the rear trim panel 50 and the rear wall structure 24.

The first pathway A₁ is defined between the rear trim panel 50 and the rear wall structure 24 and further defined between the inboard baffles 74 and the sealing blocks 75. The inboard baffles 72 and the sealing blocks 75 guide air upward over and around the jack caddy 60 toward the pathways A₂ and A₃. The pathway A₂ starts in a central area behind the trim panel 50 above the pathway A₁ and is further defined below the upper sealing edge 78 of the trim panel 50 and a corresponding one of the laterally extending seals 62. Once the exhausting air from the passenger compartment 28, a portion of the air moves through pathway A₁ and then in a first outboard lateral direction into the pathway A₂ defined the upper sealing edge 78 and the corresponding one of the laterally extending seals 62. Similarly, another portion of the air flow from the pathway A₁ moves in a second outboard lateral direction into the pathway A₃, as shown in FIGS. 3, 5 and 10. The exhausting air from each of the pathways A₂ and A₃ then moves downward toward and exhausting out a corresponding one of the drafter vent assemblies 52.

In the embodiment of the vehicle 10 shown in the drawings, there are two drafter vent assemblies 52. Since the drafter vent assemblies 52 are identical, description of one applies equally to both. Therefore, for the sake of brevity, only one of the drafter vent assemblies 52 is described hereinbelow.

The drafter vent assembly 52 is installed to the rear wall structure 24 covering and aligning with a corresponding one of the vent openings 58. The drafter vent assembly 52 includes an outer frame with a plurality of openings 52 a with a corresponding number of flaps 52 b. The flaps 52 b are also referred to hereinbelow as vent doors 52 b. Each of the flaps 52 b pivot about an upper pivot pin, as shown in FIGS. 9 and 10. When air pressure within the passenger compartment 28 is approximately the same (or less) that the air pressure outside the vehicle 10, the flaps 52 b move to the closed orientations shown in FIG. 9. When air pressure within the passenger compartment 28 increases to a level above the air pressure outside the vehicle 10, the flaps 52 b move to the open orientations shown in FIG. 10 allowing air from the air flow paths A₁ and A₂ (from the passenger compartment 28) to exhaust through the openings 52 a of the drafter vent assembly 52 (and the vent openings 58).

As shown in FIGS. 5, 7 and 11, the drafter vent assembly 52 is vertically oriented and is in contact with and abuts the adjacent one of the baffles 54, as is explained further below. With the rear trim panel 50 installed to the rear wall structure 24, the drafter vent assembly 52 and the adjacent one of the baffles 54 is concealed by the rear trim panel 50.

There are two baffles 54 installed to the rear wall structure 24. Since the baffles 54 are basically identical (mirror images of one another), only one baffle 54 is described herein below for the sake of brevity.

A description of one of the baffles 54 is now provided with specific reference to FIGS. 5-7, 11-16. The baffle 54 is installed to the rear wall structure 24 adjacent to the drafter vent assembly 52. The baffle 54 is positioned and configured to dampen sound from outside the vehicle 10 that can enter the vehicle 10 via the drafter vent assembly 52. In other words, one of the purposes of the baffle 54 is to dampen, reduce and possibly eliminate noise coming though the drafter vent assembly 52 and entering the passenger compartment 28.

As shown in FIGS. 12, 14 and 15, the baffle 54 is basically a plate member that can be formed from plastic materials, polymer materials, or any other suitable lightweight material. In the depicted embodiment, the baffle 54 is made of a corrugated plastic material that resembles cardboard material. As shown in FIGS. 13 and 16, the baffle 54 includes a pair of score lines 54 b that define a bending area such that a bent portion 54 a can be formed by bending the baffle 54 along the pair of score lines 54 b. A score line, such as a scratch or incision, is typically made with a sharp instrument in the surface of the material of the baffle 54. The pair of score lines 54 b are positioned such that the bent portion 54 a (regardless of the direction of bending) has a predetermined length, within predetermined tolerances.

As shown in FIG. 8 in phantom lines, the bent portion 54 a of the baffle 54 at the left side of FIG. 8 is bent to the left. The bent portion 54 a of the baffle 54 at the right side of FIG. 8 is bent to the right. The bent portion 54 a is dimensioned (via the score lines 54 b)

As shown in FIG. 7, the bent portion 54 a contacts a lower surface of the C-pillar 20 adjacent to the floor 22. The contact between the bent portion 54 a restricts movement of the lower end of the baffle 54 in an outboard direction. Otherwise, the baffle 54 is vertically oriented (upright) and is perpendicular to an interior surface of the rear wall structure 24. As shown in FIGS. 6 and 12, the baffle 54 contacts both the rear trim panel 50 and the rear wall structure 24, being confined therebetween. Hence, the baffle 54 defines an outboard side of the air flow path A₁ in the area of the drafter vent assembly 52. It should be understood that on the opposite lateral side of the rear wall structure 24, the baffle 54 defines an outboard side of the air flow path A₂ in the area of the other of the two drafter vent assemblies 52.

As shown in FIGS. 6, 12, 14 and 15, the baffle 54 includes a seal member S₁that extends at least part way around an outer periphery of the baffle 54. As shown in FIGS. 12, the seal member S₁ extends along the entire forward, top and rearward outer periphery of the baffle 54. Consequently, the seal member S₁ of the baffle 54 contacts the interior surface of the rear wall structure 24 and a rearward facing surface of the rear trim panel 50 creating a seal therebetween to prevent movement of air and sound.

As shown in FIGS. 5, 11 and 12, the seal member S₁ of the baffle 54 contacts the adjacent interior side surface of the C-pillar 20 and bent portion 54 a (also referred to as the bottom flap) positions the main body to contact an outboard edge of the drafter vent assembly 52.

The baffle 54 also includes a pair of attachment clips C₁ that attach to the baffle 54 via fasteners F₁, as shown in FIG. 15. As shown in FIGS. 14 and 15, the attachment clips C₁ include a curved projection dimensioned to curve around adjacent portions of the seal member S₁. The curved projection of the attachment clips C₁ includes two fastener portions F₂, as shown in FIGS. 11-12 and 14-15. The fastener portions F₂ are inserted into corresponding openings in the rear wall structure 24, fixing the baffle 54 to the rear wall structure 24, as shown in Figures.

As shown in FIGS. 2 and 3, a side trim panel of the C-pillar 20 is installed to the C-pillar 20 in a conventional manner, concealing a gap visible in FIG. 6 between an outboard end of the rear trim panel 50 and the C-pillar 20. As shown in FIG. 11 with the rear trim panel 50 removed, a seatbelt mechanism 80 is installed to the C-pillar 20. A first portion 82 a of a seatbelt extends upwardly forward of the drafter bent assembly 52. A second portion 82 b of the seatbelt extends downward and is fixed to the floor 22. The seal S₁ of the baffle 54 is visible behind the seatbelt portions 82 a and 82 b.

The vehicle components of the vehicle 10, other than various elements of the vent structure 12, are conventional components that are well known in the art. Since these components are well known in the art, these structures will not be discussed or illustrated in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the components can be any type of structure and/or programming that can be used to carry out the present invention.
